Morphologic patterns of human endometrial epithelium in women with uterine myomata treated with leuprorelin acetate

Gynecol Obstet Invest. 2010;69(2):131-5. doi: 10.1159/000264633. Epub 2009 Dec 7.

Abstract

Aim: We studied morphologic modifications of the endometrium induced by leuprorelin acetate, a gonadotropin-releasing hormone agonist, in women with uterine myomata.

Methods: Transmission and scanning electron microscopy observations were performed after 2 or 6 cycles of therapy (every 28 days).

Results: A near-normal endometrium was observed after 2 months of therapy, while treatment with 6 cycles of leuprorelin acetate induced a uniform morphologic regression of the uterine mucosa.

Conclusions: The study demonstrates that leuprorelin acetate induces a unique and time-dependent regression of the endometrial mucous membrane.
